    I have Shimano SLX BR-M675 brakes and badly need new pads. Shimano has a pad selector on their site that has you go through what type of pads you want; Resin or Metal. For each it also breaks it down to whether you want cooling fins or not, and on metal if you want Ti or steel.
    All answers are the same - J03A or J02A. Looks like both of these are resin. The J03A having cooling fins.

    Other options I should look at?

    I'm overweight and only have 160mm discs. Need braking power, but hate excessive noise which I often had with my old Avid mechanical.

    Just a 180 on front will even make a marked difference.

    It's all about 225mm rotors. :Roflmao

    Are you open to aftermarket pads? There are a lot of options out there, but as other people mentioned, going up in rotor size will help out drastically.

    Poor guy comes in here looking for brake pad recommendations and y'all are pushing bigger rotors on him when we all know he needs a new bike!! LOL


    BTW I like organic pads. More healthy!

    :eek::laugh: Ten bucks says there's a rim brake up front.

    203 f/b worked sweetly on our dirt tandems. Road tandem with the canti rim brakes plus rear drum, not so confidence inspiring...

    Thanks for the tips.
    I do need a new bike; just not in the budget since the "tax cut" cost us $7k more in taxes. (Well, that and no longer being able to claim the kid)
    Just trying to keep this old bike (2004) of mine running, when I need discs I'll look into bigger, but will need adapters I suppose.

    Looks like currently there is no J03A, but J02A is finned resin, and J04C is finned metallic.
    Pulled my old one at lunch and it's a J04C, maybe I'll stick with that.

    I'd prefer not to switch brands; just go with standard and always have it available.

    Plus 3 on 180 Rotors... I run them front and rear on all my bikes so I can buy one size fit's all.

    NEVER get me going on Avid brakes! :gag:

    Go 180's and apparently the cheap Shimano Rotors work awesome, and use the Resin with cooling fins. Everybody knows I use resin with cooling fins. The cooling fins make them... well, cooler!
    You will run faster, jump higher, and if you combine it with using Tailwinds? Oh my! There is no stopping you... EXCEPT YOUR BRAKES! <-- See what I did there?

    Some lame guys here will talk about the ones without cooling fins, and other guy will blab on about Truckers. Stick to manly brake pads and get Shimano Resin with fins and stay in the "IN" Crowd. :thumbsup::cool:

    I like the feel of both shimano resin and metallic. The cooling fin pads tend to rattle and chatter and it annoys the ever loving $@#& out of me. Not sure it would stop me from buying them but it's worth noting. If you've never noticed it before, I'm sorry if I ruined that, because once you do, you can't un-hear it.

    Never heard a peep out of my finned brakes. :unsure: That's a new one on me. What does it sound like? :coffee:

    It looks like the J04C is metallic... If it works for you, I'd stick with the same. Although I personally prefer the feel of the resin, they wear out a lot quicker.

    The 4 piston XTs I put on the Hightower came with metallic, and they get loud whenever they sense moisture in the air or when they get dusty. I have two pair of resin in the garage ready to go. If yours work, though, I wouldn't change the formula.

    I've given up caring whether it's metallic or resin. Because when I have a preference, a shop will have only the one I don't want, and the performance is not much different for my riding. To me the difference is whether the money goes into pads or rotors, and I don't care which, they're all consumables.

    Nope, still not helping you, Jim... :cautious:


    vvv Case in point. Longer lasting pads = shorter lasting rotor.

    With Shimano, I prefer metal pads because they last longer. I have not experienced any increase in squealing with metal vs. organic.

    I second this and they do make them for the SLX. I've been using them for several years. They do not have a finned pad however I have not seen any loss in performance without it.

    If you are not in any hurry I believe I have a couple sets of the stock metallic pads. I will be in the OC for the Rwanda ride next weekend if you're interested.

    I have Shimano M675 on my Nomad w/ J02A (cooling fin) resin pads. You will need a 2 piece rotor as the resin transfers heat to the rotor, instead of to the caliper like metal pads. The increased modulation from the resin is such a nice improvement over the on/off of the metal. I am a lighter rider, so YMMV, but the power is sufficient for me.

    I have been using TRP-33 (180mm) rotors with great success, instead of the more expensive Icetech option.
